• Regulatory Compliance: Identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited), indicating equivalent environmental handling requirements
• Channel Configuration: Both feature single-channel optoisolation architecture
• Product Status Advantage: TLP785(F) maintains active product status, providing long-term availability and supply chain stability

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The TLP785(F) is the appropriate selection due to its active product status. This ensures compliance with component lifecycle management requirements and guarantees long-term availability from the manufacturer.

For Existing Inventory Management: The TLP731(F) remains available in stock (896 units) and may be utilized for field service applications where existing designs are already qualified to this part number. However, transition planning to TLP785(F) is recommended to align with active product lines.

Regulatory and Compliance Alignment: Both components share identical ECCN and HTSUS classifications, eliminating export compliance complications during substitution. MSL 1 rating for both parts indicates equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TLP785(F) directly replace TLP731(F) in existing designs?

A: Substitution feasibility depends on design-specific electrical requirements. Both components are single-channel Toshiba optoisolators with identical regulatory classifications. The TLP785(F) provides documented specifications including 5000Vrms isolation voltage and transistor output configuration. Design validation against the TLP785(F) datasheet is necessary to confirm compatibility with your specific application requirements.

Q: What is the difference in packaging between these parts?

A: The TLP785(F) is supplied in Tube packaging. The TLP731(F) packaging specification is not provided in the available documentation. Confirm packaging requirements for your assembly process before finalizing component selection.

Q: Why is TLP731(F) classified as obsolete?

A: Toshiba has transitioned the TLP731(F) to obsolete status. The TLP785(F) represents the active equivalent within Toshiba's optoisolator product line, ensuring continued manufacturer support and supply availability.

Q: Are there any compliance concerns when substituting these parts?

A: No compliance concerns exist. Both components carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, and both maintain MSL 1 moisture sensitivity ratings. Substitution does not introduce export control or regulatory complications.

Q: What inventory considerations should guide my selection?

A: TLP731(F) inventory is currently available (896 units in stock). TLP785(F) inventory is also available (877 units in stock). For long-term supply chain stability, TLP785(F) is preferred due to active product status. For immediate requirements using existing qualified designs, TLP731(F) stock may be utilized.
